BELT-WHEEL.

Specification of Letters Patent. y Patented Oct. 23,1917..

Application sied May 5, 1917. serial No. 166,649.

carrying rim which is adapted to be locked to the lifelly. or fixed rim'of the wheel and released therefrom in order; that the body of the wheel may be revolvedindependently of the belt rim or vice versa. The broad object in view is to release the driven mechanism from` the ily wheel' and crank shaft of vthe driving engine, when occasion ree quires,. without throwing undue strain on the' engine or any partthereof.

f With the above and other objects in view, the invention'consists in the novel construction, combination and arrangement of parts, as herein described, illustrated and claimed. In the accompanying drawings Figure'l isa side ,elevation partly in section rof a'wheel embodying the present invention .showing the belt rim locked to the body of the wheel.

Fig. 3 is a diametrical section through the wheel.

Fig. l is a fragmentary longitudinal isection through the wheel, 'better illustrating one of the locking plungers and the operating means therefor.

lilithe, preferred embodiment oity this in-y vention, thebody of the wheelfis diametrically splitalong the' line .las yindicated in face `view Fig. 1 and 'provided kwithsuitable flanges or lugs 2 to receive bolts i3 by means of which the twinisectionsv of the fwheeljor pulley are fastened together. i f

4 designates the hub Tof the wheehf the spokes and `6 they iixed rimer felly, allot 'said yparts having ay fixed relationto each other. 'The spokes ,5 areof tubular construction each beingfformedwith a central llongitudinal bore '6' and infgthezfbores lof certain spokes- .there are vmounted flocking plungers 7 which are shown as slidable radially with respect to the center of the wheel through 'guides Swhich are threaded into the outery open ends of the bores 6. -Each plunger is'provided at its inner end with a.' head orshoulder 9 against which 'bears one end of a. coiled expansion spring 10 the opposite extremity ofl which bears against the guide 8. Therefore, the tension of the. spring 10v is exerted to draw the respective Vlocking plunger inwardly so that the outer engaging extremity 11 thereof will move vout of engagement with a corre,- sponding socket 12 in the inner face ot' a Fig. e.,

Each lookin g plunger 7 is formed between its ends with an enlargement 14 preferably noircircular .in cross section and formed in one' side thereof with grooves 15 which are pitched or inclined in a certain direction,

the enlarged portion of theplunger being provided in the opposite side thereof with other `grooves y1o which are pitched or inL clined in the opposite direction as indicated by full and dotted lines in Fig. et.

W'Vorkin'g in conjunction with the grooves or gnideways 15 and 16 just hereinabove 4described "are plunger l operating tongues,

ribs or threads 17 and 18, the tongues 17 in- 'clining in one direction to correspond with the pitch of the grooves 16, and the tongues 18 inclining .in `the opposite direction to correspond with the pitch of the grooves 15. Suiiicient spaceisleft between the adjacent tongues 17 and 18 to admit of the free movement of the enlarged portion le of the locking plungerI in order that the spring 10 may act by its expansion to withdraw they outer extremityll of the plunger from the socket 12 in the belt rim 13. i

The belt rim18 is concentric with the iixedrim or telly v6 and is supported inrelation` thereto by means of anti-friction rollers 19 which, as shown in Fig. 3, are provided with end journals 20 received Ain bearing openings in the flange 210i theiXed rim orfellybY and also in a lange22 of a detachable annular telly section 23ssecured to the main bodyy of the :telly 5 by means of fasteners 21;/ Thebelt rim 13 is formed withrabbets 25 in the opposite sides thereof normally loose belt rim 13 as best shown in tegrally with a locking ring 26 Whicliis conct tric with the belt rim 13 and lined rim 6 and located between the saine and preterably resting-on the lined rim 6 Which is tormed With an annular recess or channel 27 in which the locking ring QG moves tor a limited distance in 'either direction.

rthe means tor locking the belt` rim 13 to the tired rim 6 is illustrated in Figs. 1 Vand Q, the ring 26 being termed With an arcuate rack tace 23 which is engaged by a pinion 29 journaled in the fined rim as shown and preterably having its outer eX- tremity squared as indicated at 30 to receive a detachable operating crank 31. By the means just described, the locking ring Q6 may be turned sui'iciently to torce the locking plungers outwardly into engagement with the sockets 12 ot the belt rim 13.

' To ot the belt rim 13, the locking ring 26 is provided at one side thereot with one or more projections 32any one ot lwhich is adaptedvto strike against a shittable obstruction 33 indicated by dotted lines in Fig. 3. This obstruction 33 Will be under the control ot the engineer who when the occasion arises may cause said obstructing member 33 to be thrown into the path ot the projections 32. As soon as one ot said projections strikes against the member `33, a partial rotative nio-vement is imparted to the locking ring 26 thereby causing the locking plungers to be instantly Withdrawn trom engagement with the belt rim 13 by the cooperation ot the tongues 17, 18 and the grooves 15, 16 ot the plungers. in this Way the belt rim 13 and the tiXed rim 6 ot the pulley or Wheel are disconnected so that .one may continue to revolve inc ependently ot the other which may be brought to a stop. The detachable telly section 23 is tormed with arcuate slots 3i which admit 'ot the necessary movement ot the projections 33 and the locking ring 26 and limit such turning movement in either direction. The belt rim 13 and also the locking ring 26 are p'reterably split as indicated respec- Atively in Figs. 5 and 6, being tormed With overlapping portions 35 and 33 through which are inserted bolts 37 or equivalent fastening means. By reterence to Fig; 2 it will be observed that in providing the inclined tongues 13, Wherever they occur, the locking ring 26 is termed with a longitudinal slot 33 in which the enlarged portion 1-1 yot the adjacent locking plunger is mounted, the tongues 17 and 13 being arranged at opposite sides 'ot the slot 33 so as to engage the grooves 15 and 16 inthe opposite taces ot' the enlargement 14 ot the locking plunger.V

From the toregoing description, talren in connection Vwith the accompanying drawings, `it will now Vbe understood that preproyide tor the instantaneous release paratory to Vstart-ing the engine, the belt carrying rim 13 is locked in tixed relation to. the tired rim Ior telly ot the Wheel by placing the detachable crank 31 on the outer end ot the shatt ot the pinion 29 and turning the latter so as to impart a partial rotative movement to the locking ring '26. The latter then thrusts outwardly all ot the locking plungers 7 by the coaction between the tongues on the looking ring and the grooves in the enlargement 1lthus causing the outer ends 11 ot the locking plungers to enter and be held in the socketsl. in order to releasethe engagement between the :belt rim `and the tired rim, the 'obstructing 'member 33 is thrust -in-to the path ot the projections 32. This will result in holding back the -locling ring ysutciently to release tbe .locking` plungers which yare immediately drawn inwardly by the springslO. Eachot the projections32 is .preterably beveled on both sides thereot :as shown at 39 tolprevent :breaking ed said projections during the last named yopt-3ration. Y
